The earliest recollection of this bug is traced back to PAN-OS 11.1.10-h5 - February 04, 2026. This bug is fixed in PAN-OS versions 11.1.6-h19, 11.1.12, 11.1.10-h7, 12.1.4, 11.2.10, 11.1.10-h5. Fixed an issue where a local commit on a firewall breaks template stack overrides, preventing the enabling of LACP (Link Aggregation Control Protocol). After a local commit, the LACP enable check was unexpectedly unchecked, causing an outage. Attempting to re-enable LACP through the web interface was unsuccessful, requiring manual removal of the LACP configuration from the Panorama CLI.
